Fig. 5: Correlation between perceptual responses and ocular following responses.
From: Distinctive feature sensitivity of ocular following initiation during global motion perception
a Time courses of correlation between perceptual estimations and eye movements for 12.5 ˚/s of global motion in Carrier+Envelope condition. Green shaded area represents mean ± SEM across participants. The left panel shows the speed correlation, and the right panel shows the direction correlation. Gray lines depict individual participant data. The red line with shaded area in plot with thick red line at the bottom indicates a significant time cluster (p < 0.001, cluster-based permutation test). b, c Comparison of correlation coefficients between the early phase (100–172 ms, initial eye movements) and the later phase (194–266 ms, defined by the significant time cluster). b Group data. Gray dots represent the mean correlation for each participant. Error bars indicate ±1 SEM. The asterisk denotes statistical significance (p < 0.001). c Scatter plots showing the relationship between perceptual estimations and eye movements for speed (left two panels) and direction (right two panels) during the early and later phases, respectively. Individual trials are shown as colored points, where each color represents a different participant. The red line indicates the grand regression line across all participants, while the gray lines show individual regression lines.
